A simulation of a pebble bed reactor core by the MCNP-4C computer code [PDF]
Nuclear Technology and Radiation Protection, 2009 Lack of energy is a major crisis of our century; the irregular increase of fossil fuel costs has forced us to search for novel, cheaper, and safer sources of energy. Pebble bed reactors - an advanced new generation of reactors with specific advantages in

Medical Physics, Volume 52, Issue 9, September 2025.Abstract BackgroundAlzheimer's disease (AD) is characterized by the accumulation of β$\beta$‐Amyloid and τ$\tau$ proteins in the brain that causes dementia. To date, there is no cure capable of eradicating AD, so it is necessary to study a performing therapy.

Operation of a 1-Liter-Volume Gaseous Argon Scintillation Counter
, 2009 We have built a gas-phase argon ionization detector to measure small nuclear recoil energies (< 10 keVee). In this paper, we describe the detector response to X-ray and gamma calibration sources, including analysis of pulse shapes, software triggers ...

Non‐compliant neutron dose associated with an internal lead slab in a radiotherapy treatment vault
Journal of Applied Clinical Medical Physics, Volume 26, Issue 8, August 2025.Abstract Background In high energy radiotherapy treatment vaults, photoneutrons can be produced by direct photon interactions with barrier materials and have a mean energy of approximately 20% of the nominal photon energy. Excess photoneutrons outside a treatment vault are always a concern due to their significant radiobiological efficacy, or Q value ...
